Bigger wheels or discs will make deeper cuts.If you have a concrete slab that is three inches thick, a 4.5-inch wheel will not cut through it, because the 4.5 inch wheel only sticks out at half the diameter or only 2.For this project you will need a larger grinder, such as the 9-inch model, which extend out at 4.
